What are the best practices for using routing guards in Vue.js?

When using routing guards in Vue.js, it's important to keep your guards simple, avoid unnecessary complexity, and ensure they are reusable.

Can you explain the difference between global and per-route guards?

Global guards apply to all routes, while per-route guards are specific to individual routes. Use global guards for authentication and per-route guards for route-specific logic.

How can I handle asynchronous operations in routing guards?

You can return a Promise in your guard to handle asynchronous operations. This allows you to wait for data fetching or authentication before navigating.

What should I do if a guard fails?

If a guard fails, you can redirect the user to a different route or show an error message. Make sure to handle these cases gracefully.

Are there any performance considerations I should be aware of?

Yes, avoid heavy computations in guards and minimize the number of guards to improve performance. Use caching where possible.
